Mitsui O.S.K. Lines (MOL) has completed Japan’s first ship-to-ship methanol bunkering operation at the port of Yokohama, marking a significant step in the country’s efforts to support alternative marine fuels.
The operation involved the safe transfer of methanol between vessels under controlled conditions, demonstrating the feasibility of methanol as a marine fuel within Japan’s port infrastructure. MOL said the bunkering was carried out in compliance with relevant safety and environmental standards.
Methanol is being explored by shipping companies as a lower-emissions alternative to conventional marine fuels, particularly for next-generation dual-fuel vessels. The successful operation is expected to support the wider adoption of methanol-fuelled ships in Japanese waters.
MOL said the milestone aligns with its decarbonisation strategy and its broader commitment to achieving net-zero greenhouse gas emissions. The company plans to continue collaborating with partners to develop alternative fuel supply chains and bunkering capabilities.
Industry observers said the development strengthens Japan’s position in supporting cleaner shipping and alternative fuel infrastructure.
